The Dow Jones-AIG Commodity Index is composed of 19 futures contracts on physical commodities and was introduced in 1999. The DJ-AIGCI family of indexes includes nine sector sub-indexes, multiple forward month indexes, sub-indexes for each individual commodity in the original DJ-AIGCI, Euro-, Yen-, Swiss Franc-, and British Pound-denominated versions of the Dow Jones-AIG Commodity Index, and the Dow Jones-AIG Commodity Spot IndexSM. Also available are total return versions of each of the excess return indexes and sub-indexes. As of the end of the fourth quarter of 2007, we estimate there is $42 billion tracking the DJ-AIGCI, out of a total of approximately $145 billion tracking commodities using long only index strategies.
